During the end of the seventies and the beginning of the eighties of the last century, the Groningen pop music was at its height. Herman Brood was the ‘instigator’ of this Groningen Springtij (Spring Tide). He stimulated other bands like Whity Honey, Jan Rot & the Streetbeats, Phony & the Hardcore, The Meteors, Subway, AA & The Docters, New Adventures, Splitsing, and the Rocking Tigers. Spring Tide by Frank & Lisa was made as part of the manifestation ‘Cha Cha the phenomenon Herman Brood’. They have made a paste-up on the basis of video recordings from the collection GAVA/RHC Groninger Archieven of Springtij bands like AA & The Docters, Speedo, Splitsing and Red Knobs and recordings of street images, demonstrations, commercials, fashion trends and design.
